Managua , Nicaragua -LRB- CNN -RRB- -- Nicaragua 's election officials have officially declared President Daniel Ortega 's victory , but opponents are protesting the results .

A report from the Organization of American States indicated `` irregularities in the elections , '' but supported official results saying that Ortega won re-election after garnering more than 62 % of votes .

`` A process is legitimate if the people feel that there wishes were respected , and that is what we are experiencing here , '' said Roberto Rivas , president of Nicaragua 's election authority .

But protests and clashes throughout the country after the November 6 elections have left at least four people dead and dozens injured , police said .

According to a report presented by the Organization of American States ' election observers , irregularities during elections included problems providing identification card to vote , problems in the accreditation of observers and imbalances in political parties present at polling stations .

For opponents of Ortega , the report shows evidence of fraud .

`` Obviously here transparency is missing . They did n't take a series of legal steps that they should have , '' said Eduardo Montealegre , a representative from the opposition Independent Liberal Party .

The Organization of American States says its vote count echoes the official election results .

But one local pro-democracy group says the problems the organization identified would equally impact their own tallies .

`` It 's not that the results changed on the way -LRB- to be counted -RRB- , it 's that the absolute power of the councils overseeing the polls did not allow any challenges , '' said Roberto Bendana , president of We Make Democracy .

Last week U.S. State Department spokeswoman Victoria Nuland weighed in over reports of procedural irregularities and voter intimidation .

`` Frankly , if the Nicaraguan government had nothing to hide , it should have allowed a broad complement of international monitors , '' she told reporters in Washington .

Disputes over the results have caused confrontations between protesters and authorities , said Marcos Carmona , executive secretary of Nicaragua 's Permanent Human Rights Commission .

`` We have reports from different citizens about aggression on the part of the National Police , '' he said , including the deaths of a father and two sons .

Last week a National Police spokesman said the three had died during clashes with supporters of Ortega 's Sandinista party , adding that protesters had provoked clashes with police .

`` As the National Police , we reiterate our call to the activists and directors of the different political parties , to not use violence and to express their positions through civic means , respecting , above all , the lives of others , '' police spokesman Fernando Borge said .

Ortega was first elected as Nicaragua 's president in 1984 , and ran unsuccessfully in 1990 , 1996 and 2001 before being elected again in 2006 .

He is known as an ally of Venezuelan President Hugo Chavez and was a public supporter of former Libyan leader Moammar Gadhafi during the Libyan uprising .

But recently he has reached for the middle , making overtures to the business class and promising to lure foreign investors into the country .

His third term is scheduled to begin January 10 . But opposition representatives say they plan to dispute election results before international organizations .
